ATTACHMENT FOR TYPE-WRITERS.

Application filed August 13, 1902.

.useful Improvement in Attachments for Type- Writers, of which the following is a full, clear,

and exact description, referencebeing had to the accompanying drawings.

The object of this invention is to provide in very simple and eflicient form devices adapted.

to be attached to a type-writer for temporarily stopping the carriage at any desired point,

.. allowing the carriage to thereafter proceed on its course. Theinvention is thus of a special value in tabulating work, where it is desired after matter has been written to skip a distance and then begin figures in a certain col- A more p i c o ie t of t ln n qn 18 t and conveniently adapted for attachmentto an .br i ary ypew ro t iem netq s le- Theinvention, maybe best summarized as c s st g o the o bi n and P r s t the above ends, as hereinafter more fully, ex-

The "drawings clearly show my invention as a i applied to a Remington type-writer.

F gu 1 isa p a of th upper p ti n of such type-writer, Fig. 2 is an end view, partly in section,of such portion. Fig. 3is a face view of the escapement wheel and bar. Fig. {i is a.

perspectiye View of onemember ofmy stopping device. Figs. 5 and 6 are views of the other member of my stopping device in place on themarginal stop-bar of thetype-writer, Fig. 5 being a sectionon the line 5 5 of Fig. 2 and Fig. 6 being a front elevation.

Referring to the parts by letters, represents the frame of the type-writer.

, B is the front portion of the traveling carriage carrying theplaten B andpivoted to a K rear portion C, which hasrollers'c, bearing on a rod (0, carried by the frame, and hasa guiding-arm 0, taking around a rod a, carried by the frame. Pivoted to the portion (J of the carriage at (Z are arms d",to the front edge of which is secured the escapement-bar D. This bar meshes with teeth on the escape- Serial No. 119,481. =(No model.)

' ment-wheel E on the forward end of the shaft 6, journaled in the housing 6 and having at its rear end a wheel e, with which the escapement-dogs (not shown) may be operated. The carriage is given a tendency to move to the left by the strap H,taken around a springdrum. (Not shown.) To allow the carriage to be shifted, there is pivoted to the portion B at ported by the frame; These marginal stops are not 'shown. In use they areadjustable .alongthe bar G and form a positive stop to the carriage by the engagement of the bar of, whether the escapement-bar Dis in engagement with its pinion E or not. V v t The construction above set out is of the ordinary Remington form and is described thus fully simply for clearness in explaining the operation of my stopping device, which will now be described.

On the marginal stop-bar G of the typewriter I place a stop J, and on the arm d I secure an extension K. This extension extends over the bar G and when the escapement-bar D is in engagement with the pinion E stands high enough above the bar G to clear the stop J. This clearance of the stop when the escapement is in engagement is' one of the features of this invention wherein it differs from the marginal stops heretofore'employed, and

it is this clearance which allows my operation,

for when the escapement-bar is raised to allow the carriage to be shifted the extension-arm Kengages the stop J and stops the carriage; but as soon as the escapement-bar is thereafter lowered, coming into engagement with its pinion, the arm K is raised sufficiently to pass over the stop J, so that the type-writing may be continued.

The stop J consists in its preferred form I00 l of a small sheet-metal plate bent into a U shape, having bent upward from its intermediate portion the lip f and having bent inward from its rear portion the tooth 1' the rear portion being bent outwardly at y", where there is pivoted the latch j, adapted to take into a notch from the depending portion 1' on the front side of the stop. The stop is readily removable by turning the bar a quarter of the way back and may thus be placed in any position desired, and when so placed it is readily held by the tooth j engaging the notches on the rear side of the margin-bar G, while the latch-bar j holds the stop snugly down onto the barG. A

The extension-arm K is formed of a sheetmetal plate bent over into the flat tubular form shown in Fig. i. This form provides a tapered horizontal opening it, which the flat portion of the arm d may occupy, while along the side of this is a downward opening 70 through which the downward projection on the arm d may pass. The extension K has a projection 70 adapted to stand above the margin-bar G. Taking into the extension K are a pair of set-screws k, which clamp it to the arm 6Z2. This extension is thus readily removable, but is easily put in place, being slipped over and clamped to the peculiarlyshaped arm 61 having a downwardly-extending lip, such as is common on type-writers of the Remington type, and requiring no alterations whatever of such arm to carry the extension.

In using my stops the stop J is placed on the margin-bar (which has a scale upon it) at the position corresponding to that on the paper where the column is to begin. Then after the matter preceding the figures has been written the lever F is depressed and the carriage shifted to the left until the arm K en gages the stop J. Then the hand is taken oif the lever F and the carriage is in position to is out of engagement, substantially as described.

2. In a type-writer, the combination of a frame, a stop-bar carried thereby, a carriage mounted to travel along the frame, a pivoted escapement-bar mounted on the carriage, an escapement carried by the frame and adapted to engage said escapement-bar, an arm extending rearward from said escapement-bar to a position directly over said stop-bar and some distance above the bar, and a stop carried by said stop-bar and having a lip extending upward from the upper surface of the bar, the upper end of the lip being out of the path of the armwhen the escapement-bar is in engagement but being in such path when the escapement-bar is out of engagement, substantially as described. I

3. In a type-writer, the combination of a frame, a bar carried thereby, a stop mounted on said bar, a carriage mounted to travel along the frame, a pivoted escapement-bar on the carriage, an escapement carried by the frame for engaging said escapement-bar, an arm extending rearward from said escapement-bar, an extension-arm removably carried by the aforesaid arm in a position to engage the stop when the escapement-bar is out of engagement, and means for securing said extensionarm in place, substantially as described.

4. A stop for a type-writer consisting of a U-shaped plate having an upwardly-extending lug, an inwardly-extending tooth, and a latchbar pivoted to one leg of the U and adapted to engage the other leg, substantially as described.

5. The combination with a notched bar of a type-writer of a stop made by a U-shaped plate, having an inwardly-extending tooth and having one of its legs turned outward, and a latchbar pivoted to said outward extension and adapted to occupy a notch in the other leg.

6. A stop for a type-writer consisting of a U- shaped plate having the edge of its intermediate portion turned upward to make a lip f and having the edge of one of its legs turned inward to make. an internal tooth f and having the lower portion of said leg turned outward as at y", and a' latch-bar j pivoted to this outward extension and adapted to occupy a notch in the other leg j which depends below the latch-bar, substantially as described.

7 The combination with a type-writer having an extending arm with a projecting lip, of an extension made tubular and adapted to slide over said arm, and means for rigidly securing said extension thereto, substantially as described.

8. The combination with a type-writer having an extending arm with a downwardlyturned lip, and an extension made tubular and provided with an opening on its under side near one edge to allow the passage of said lip whereby the extension may be slid over said arm, substantially as described.

9. The combination with a type-writer having an operating-arm, of an extension thereof consisting of a body-plate, a downwardly-projecting wing at an angle thereto, said bodyplate being bent backward upon itself so as to form a flattened tubular portion, said bentback portion being on the under side of the body-plate, and means for holding said extension to said arm, substantially as described.

10. An extension-arm for a type-writer con- 10 ing 70 upon its under side near one edge, said extensionarm having a Wing k formed by turning downward the free edge along the side of said opening, substantially as described.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
